Chrysanthemum plant named ‘Fimmsungol’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Fimmsungol’, characterized by its compact, upright to outwardly spreading and uniformly mounded plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; medium to large decorative inflorescences with bright yellow-colored ray florets; mid-August flowering response under natural season conditions; and good garden performance.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘FIMMSUNGOL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a garden Chrysanthemum and hereinafter referred to by the name ‘Fimmsungol’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Fareham, Hampshire, United Kingdom. The objective of the breeding program is to create new early-flowering garden Chrysanthemum plants with numerous attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination made in January, 2007 by the Inventor in Fareham, Hampshire, United Kingdom of a proprietary selection of Chrysanthemum×morifolium identified as code number 3030, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number 3137, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Fareham, Hampshire, United Kingdom in September, 2007.

Asexual reproduction of the new Chrysanthemum by terminal vegetative cuttings was first conducted in Fareham, Hampshire, United Kingdom in December, 2007. Asexual reproduction by terminal vegetative cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Fimmsungol’. These characteristics in combination distinguish ‘Fimmsungol’ as a new and distinct Chrysanthemum plant:

-   -   1. Compact, upright to outwardly spreading and uniformly mounded         plant habit.     -   2. Freely branching habit; dense and full plant habit.     -   3. Uniform and freely flowering habit.     -   4. Medium to large decorative inflorescences with bright         yellow-colored ray florets.     -   5. Plants flower under natural season conditions during the         third week of August in the United Kingdom.     -   6. Good garden performance.

Plants of the new Chrysanthemum can be compared to plants of the female parent selection. Plants of the new Chrysanthemum differ from plants of the female parent selection, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum flower about one month         earlier than plants of the female parent selection under natural         season conditions.     -   2. Plants of the new Chrysanthemum and the female parent         selection differ in ray floret color as plants of the female         parent selection have pink-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the male parent selection. Plants of the new Chrysanthemum differ from plants of the male parent selection, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum have larger inflorescences         than plants of the male parent selection.     -   2. Plants of the new Chrysanthemum flower later than plants of         the male parent selection under natural season conditions.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Conaco Yellow’, not patented. In side-by-side comparisons conducted in Fareham, Hampshire, United Kingdom, plants of the new Chrysanthemum differed from plants of ‘Conaco Yellow’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum had lighter green-colored         leaves than plants of ‘Conaco Yellow’.     -   2. Plants of the new Chrysanthemum flowered about one month         earlier than plants of ‘Conaco Yellow’ under natural season         conditions.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum. The photograph comprises a top perspective view of a typical flowering plant of ‘Fimmsungol’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the late summer and early autumn in 19-cm containers in an outdoor nursery in Fareham, Hampshire, United Kingdom and under cultural practices typical of commercial garden Chrysanthemum production. During the production of the plants, day temperatures ranged from 10° C. to 25° C., night temperatures ranged from 5° C. to 15° C. and light levels ranged from 400 to 2,500 joules. Plants were pinched one time and were about 14 weeks old when the photograph and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
